Common Femoral Artery Curvature During Hip Flexion.

PURPOSE: To assess the conformational changes of the common femoral artery (CFA) during hip joint flexion in patients without atherosclerosis. METHODS: Patients who underwent digital subtraction angiography for suspicion of arterial endofibrosis between 2007 and 2011 were retrospectively searched. Angiographic images were analyzed by two independent readers. The CFA was divided into four segments of equal length, and the segment containing the folding point was noted. Segments 1 and 2 were located in the proximal half of the CFA and segments 3 and 4 in the distal half. Readers assessed the CFA angulation, located the arterial folding point, and classified the CFA curvature as harmonious, or as a moderate or severe plication. RESULTS: Forty patients were included. The Lin concordance correlation coefficients, used to evaluate inter-observer variability, were 0.90 (95% CI [0.83; 0.96]), 0.96 (95% CI [0.93; 0.98]) and 0.96 (95% CI [0.94; 0.98]) for the measures of the CFA angle during flexion, of the length between the superficial circumflex iliac artery and the folding point, and of the length between the folding point and the femoral bifurcation, respectively. The CFA curvature was described as harmonious in 12 patients, moderate plication in 14 patients, and severe plication in 14 patients. The CFA folding point was located on segment 1, 2 and 3 in 6, 26 and 8 patients, respectively; no folding point was located on segment 4. CONCLUSION: In these patients with non-atheromatous disease, hip flexion yielded most frequently a harmonious curvature or a moderate plication of the CFA.

[Shaving of popliteal artery secondary to a knee arthroscopy]. / Cas clinique. Lésion iatrogène de l'artère poplitée lors d'une arthroscopie du genou.

Popliteal artery lesions are rare complications of knee surgery and may have significant sequelae depending on the length of time it takes to diagnose this type of vascular injury. We present two case reports of popliteal artery following meniscus resection by shaving.

Les cas de lésions iatrogènes de l'artère poplitée liées à la chirurgie orthopédique du genou sont des complications rares, qui peuvent entraîner des séquelles importantes en cas de retard dans le diagnostic de ce type d'atteintes vasculaires. Nous vous présentons deux cas particuliers de plaie de l'artère poplitée à la suite d'une résection des ménisques lors d'une arthroscopie.
